Thanks but it didn't help...I even had a friend logging into my account remotely from his desktop and encountering the same issue. Called into Turbotax support and the technician said apparently, we can amend the previous tax return online after April of last year...which is really puzzling because the button is there! Also, when I googled, there are literatures that mention one can do so up to 3 years online using Turbotax...maybe that has changed but, it's a pain because now I have to use the desktop Turbotax software to amend the report and then manually enter the information when doing 2021's return because if I import the .tax file from the amendment I've made for 2020, I'll lose everything I've worked on 2021 so far I believe.
Anyways, 4 hours of run around for nothing...that "Amend 2020 tax online" button should not be there if we're not able to do so. I guess that's the cost for trying to save $$$ vs.paying for an actual accountant...
